Parts for your 2025 Mitsubishi Asx-Struts

2025 Mitsubishi ASX struts: what they do and when to service them

Struts are relevant and fitted to the 2025 Mitsubishi ASX. Technical references that specify a MacPherson strut front suspension include the Mitsubishi ASX workshop manual for the GA-series platform (also sold as RVR/Outlander Sport), Mitsubishi Motors Australia model specifications listing “MacPherson strut” for the front suspension, and the EU-market 2025 ASX (based on Renault Captur II) technical data, which also confirms a MacPherson strut front layout. Rear suspension uses a separate spring-and-shock arrangement (torsion beam or multi-link depending on market/grade), so the “strut” terminology applies to the front.

On the 2025 ASX, the front strut is a structural assembly that combines the damper, coil spring, and upper mount/bearing. It supports the vehicle’s weight, controls body movement over bumps, and locates the wheel hub to hold camber and caster steady. Because the strut carries steering loads, its condition affects straight-line stability, braking bite, and tyre wear.

As part of routine servicing, it’s smart to inspect the struts every 20,000 km for oil seepage, dented tubes, split dust boots, sloppy or noisy top mounts, and uneven or cupped tyre wear. Many owners find replacement due between 80,000 and 150,000 km depending on road quality and load. If one front strut is tired, replacing in pairs keeps the ASX balanced under brakes and through corners.

When replacing, a quality spring compressor and the right procedure are essential, as the coil stores a lot of energy. It’s a good time to renew the strut mounts, bearings, bump stops and boots. Torque all fasteners to spec with the vehicle at ride height where required, and book a wheel alignment immediately afterward. On models with advanced driver assistance, a steering angle or camera/radar calibration may also be needed after front suspension work.

Drivers will usually notice clues when the ASX’s struts are on the way out: extra bounce after speed humps, front-end clunks over potholes, longer stopping distances, steering shimmy, or the car wandering on the motorway. Keeping the struts in top nick preserves tyre life, sharpens steering feel, and makes daily commuting or a weekend trip across the Tasman a lot more relaxed.

• Typical service checks: leaks, mount play, dust boots, tyre wear pattern, road test bounce/feel
• Best practice: replace in pairs, renew mounts, align wheels, verify ADAS calibration if equipped

Do the 2025 ASX models actually have front struts?

Yes. Both the long-running ASX sold in Australia/NZ and the EU-market Captur-based ASX use MacPherson struts at the front. The rear uses separate shocks and springs, so “struts” refers to the front axle hardware.

How often should ASX struts be replaced?

There’s no fixed interval, but inspection every service is wise. Many struts give solid service to around 80,000–150,000 km. If there’s oil leakage, noisy mounts, poor ride control, or uneven tyre wear, it’s time to plan a pair replacement and a wheel alignment.

Can worn struts damage tyres or affect safety systems?

They can. Weak damping and sloppy mounts cause cupped or rapid tyre wear and can lengthen stopping distances. After front-end work, a correct alignment is essential, some models may also require ADAS calibration to keep lane and braking assists working properly.
